Cut each pita pocket into 8 triangles by halving it, then cutting each half into quarters. Separate the layers if possible for extra crispy chips.
In a medium bowl, combine the cinnamon, sugar, and salt.
Brush each pita triangle lightly with melted butter.
Toss the buttered pita pieces in the cinnamon sugar mixture until evenly coated.
Preheat your air fryer to 350°F (175°C) for 3 minutes.
Arrange the Air Fryer Cinnamon Pita Chips in a single layer inside the basket without overlapping.
Air fry for 6–8 minutes, shaking the basket halfway through cooking.
Watch carefully during the last minute since they can brown quickly.
Transfer to a wire rack and allow the chips to cool completely before serving or storing.
